Last summer Casio revised the SGW400H, itself an ana-digi-upgraded revision of SGW300; by a rearrangement and slight cleanup of the dial together with hands and color changes to come up with the new SGW450H lineup.
Both lineups have that not so common quality of equally legible analog and digital displays with an analog overlay which manages to keep interference with digital to a minimum. Dial and hands overhaul on the new SGW450H only enhances this ana-digi separation to make 'em each ever easier to read with the possible exception of the Pressure Differential Level indicator which was made a lot smaller to improve on the layout of the other displays. This is what attracted me to SGW450H and though I think the metallic SGW450HD-1B is by far the best-looking version, I went with the SGW450H-1A for its positive display practicality.
At 50.8 x 51.9 x 14.9 mm / 51 g this is a rather sizable albeit lightweight piece with a slightly diminished version of that chunky-but-light G-Shock feel on the wrist. And that can only be a good thing. The band is thin, pliable and very comfortable, it does a great job of keeping the case in place without a tight death grip on the wrist.
First push of MODE gets you to BARO with air-pressure and temp in your choice of imperial or metric plus digital Current Time.
The stark white hour markers stand out prominently in the light
...Only to disappear in darkness as they're not lumed. Lumed tips of the hands are surprisingly, for Casio, all-night long-lasting but they're all but impossible to tell apart or even orient correctly in the sleepy dark. The non-auto EL backlight is cool and reliable if a bit short-lived at its longest 3 seconds.
Second MODE push delivers World Time. Digital Current Time stays put at upper right.
...And CDT are at third and fourth MODE press respectively.
The 5 Alarms are arrived at the 5th MODE press. The alarm sound though of moderate volume is so dull and monotonous as to induce further sleep rather than prompt wakefulness. Much like non-electric lume, this is another area that seems to escape Casio's attention and field-testing every time, only to be added as a mindless and therefore mind-bogglingly dysfunctional afterthought.
Still, this is an affordable, handsome, easily legible ana-digi with 24-hr stopwatch and timer and a simple alti-baro function.
At A Glance
High quality sports looks, backed by a rich feature set, define the SGW450 Twin Sensor from Casio. The watch takes and displays barometric pressure readings, which are then converted into Altitude measurements based on International Standard Atmospheric Values. A built-in thermo sensor gives reliable temperature readings. Combining these sensors with a rugged case design, ana-digi display and a host of additional features makes this watch tough to beat.
